Exotronic 350A Single Circuit ON-OFF Battery Switch

Reliable High-Current Isolation for Marine and Automotive Electrical Systems

The Exotronic 350A ON-OFF battery switch provides a robust and dependable method for isolating a single battery bank from a single load group. Engineered for demanding environments, this switch is an essential component for managing high-current DC circuits in marine vessels, recreational vehicles, and off-grid power systems. With a continuous current rating of 350 amps and a peak rating of 600 amps for up to 5 minutes, it handles substantial inrush currents from engine starters and heavy auxiliary loads without compromising performance or safety.

Unlike generic switches that may fail under sustained high loads or in corrosive environments, the Exotronic battery switch is built with durability in mind. Its IP66-rated sealed housing protects internal contacts from dust, moisture, and salt spray, making it suitable for installation in engine compartments, exposed deck areas, and coastal environments. The ignition-protected design adds an extra layer of safety, allowing use in petrol engine spaces where flammable vapours may be present.

Key Features

  • 350A continuous rating with 600A peak (5 min) for demanding engine start and high-load scenarios
  • IP66 weatherproof construction resists water, dust, and salt corrosion for long-term reliability
  • Ignition protected for safe installation in petrol engine compartments
  • 3/8"-16 (Approx. M10) stud terminals accept heavy-duty lugs up to 4/0 AWG (approx. 95mm²) for secure, low-resistance connections
  • Compact footprint (98 x 98 x 80 mm) with recessed mounting holes for flexible installation
  • Clear ON-OFF position indicators for quick visual confirmation of circuit status
  • Ergonomic rotary actuator allows easy operation even with wet or gloved hands

Built for Harsh Australian Conditions

Marine and off-grid environments demand components that can withstand vibration, temperature extremes, and corrosive elements. The Exotronic 350A switch features a rugged, UV-stabilised housing and stainless steel hardware that resists rust and degradation. The fully sealed design prevents internal corrosion, a common failure point in lesser switches, ensuring consistent performance over years of service. Whether you're navigating coastal waters or traversing dusty outback tracks, this switch maintains reliable electrical isolation when you need it most.

Simple Installation, Secure Connections

Designed for straightforward integration, the switch includes recessed mounting feet that allow surface mounting on panels, bulkheads, or battery boxes. The large stud terminals accommodate heavy-gauge battery cables, minimising voltage drop and heat buildup under load. The rotary knob provides a positive, tactile switching action, reducing the risk of accidental operation. For added safety, the terminals are recessed to help prevent short circuits during installation and maintenance.

Applications

This single-circuit ON-OFF switch is ideal for isolating a single battery bank in a variety of setups:

  • Marine vessels: inboard petrol or diesel engines, trolling motors, house battery isolation
  • Recreational vehicles: auxiliary battery disconnect for caravans, camper trailers, and motorhomes
  • Off-grid systems: solar battery banks, backup power systems, remote equipment
  • Automotive: secondary battery isolation in 4WDs, trucks, and work vehicles
  • Industrial: emergency stop isolation for DC machinery and equipment

Why Choose Exotronic?

Exotronic battery switches are designed to meet the real-world demands of Australian users. By combining high current capacity, robust environmental protection, and user-friendly operation, this switch reduces the risk of electrical failure and enhances system safety. It provides peace of mind, knowing that your battery can be quickly and reliably disconnected for maintenance, storage, or emergency situations.

Upgrade your electrical system with the Exotronic 350A ON-OFF battery switch and experience the confidence of a secure, high-performance isolation solution built for the long haul.

Great Multi-Function Watch
Color: Gray/Digital/Gray
I absolutely love my Timex Ironman watches. I have had many over a very long period of time. Wonderful set of functions for the price. Very affordable. Easy to use. Lasts a long time. Very easy to read in standard lighting. I like the Indiglo when needed, but do not use it too often. Absolutely love the ability to set a repeat timer to remind me to do something at a fixed interval, or to keep me on task for a fixed period of time. Great to be able to set three independent alarms. Potential to capture a huge number of splits with the stopwatch. I purchased this watch to replace a similar model with a dead battery. I have replaced batteries in the past, but it is quicker and easier to buy a replacement watch. I am saving my old watches for that day in the future when the Ironman model may no longer be available. I expect this will be my watch of choice for the rest of my life.

Just fine if you have simple needs...
Color: Black/Digital/Black/Green
Exactly what I needed: a cheap, durable wrist watch. The only thing it was lacking were instructions, but about 5 minutes of messing with the buttons got it set up

Compared to g-shock?
Color: Black/Yellow
Firstly random public reviews can be comical…”it’s has a battery, terrible, One star” or “I don’t like yellow, one star” omg peoples do better. I’ll review this while comparing to an older style of g-shock from the same era. I’ll start by saying this timex rocks, for me in my mid 50’s it’s so retro and nastalgic, brings back memories, I may have even owned this model back in the day. What’s great about it- the display, larger digits than the typical g-shock and they are super crisp, clear and easy to read. The indiglo is awesome. This is the most accurate quartz watch I have aside from the atomic g-shocks that adjust themselves daily. I prefer a chunky watch and the g-shocks do a better job in that department. i feel this watch is rugged, but I’d still give the nod to g-shock in this department. 200M water resistance is the gold standard and this watch has it which I love for peace of mind for any water based activities. This is a 5 star watch at a great price. I still love some aspects of a g-shock better but its just preference.

Everybody loved the high-tech style and amazing functionality
Color: Black/Yellow
I'm not a Timex fanboy, and I've had my fair share of problems with the Expedition line, so this review is my honest opinion as a man who's worn Armitrons and Timexes since I was 10. I remember in 1992 when the Timex Ironman Triathlon with Indiglo was first launched - My older brother got one, then me and my neighbor friends. Everybody loved the high-tech style and amazing functionality. Even Bill Clinton was rock'n this watch, for those who don't remember. Quite simply, this is the perfect watch at a great price, in my opinion. Perfect as a gift for any man, and I think the original black/olive drab/yellow coloration is still the coolest. In this day and age of smartphones, it still pays to have this watch. The alarm is less annoying sounding than a cellphone, and doesn't wake up the entire house. To turn it off, just tap the watch, no more reaching for the phone or alarm clock. Timer comes in handy for anything; timing my kids' timeouts when they get in trouble, 15 minutes room clean-up times, etc. Chrono is fun for anything you wanna use a stop-watch for. I set the second time zone for Vietnam time. It really is a million times easier to use this watch for all of its functions than reaching for a smartphone or alarm clock, etc. If you;ve been relying on your phone for a few years as a watch/chronograph/timer/alarm - you'll be so glad you finally got a watch like this. I've never tried a smart-watch, however I feel those are not as necessary,durable or practical as a real watch. Other Timex watches I've used were freakin' trash - couldn't throw em away fast enough. Might as well open the box while holding it over a trash can, so the watch can fall right in when you open the box. That's my experience with the Expedition line-up. Back to this watch: The only thing I wish this watch could do is measure activity thermogenesis (calories expended throught the day) or work as a pedometer, which some smart-watches and other devices can do. I also cannott decide if I like this new, slightly larger, heavier/thicker design of the Ironman Triathlon over the 1990s design. The 90s models styling was "tight to death'. Star-split buttons were seperated. The mode button was yellow. Overall more compact and bi-cultural;by that I mean it looked great as an athletic watch or a politician, business man wathc. This new model is bigger, better ingress/shock resistance, and more of an athletic style over all, and is a little less colorful. I almost went with the G-shocks, but they still just look like crap and are waay to expensive. Sure, they have some better features, can survive WWIII, but I am a traveler. I need a watch that can work in the dark in any environment. The G-shocks are often using some kind of solar battery crap and rely on cathing a signal from an American automic clock in Colorado - good luck with that while your in Thailand on vacation.
